Does anyone know of this performance issue on ISR 3845 router. Your help will be greatly appreciated. Here is the issue:
I have been told that if I have a ethernet switching module on the router and do mls QOS config between the switch module and the router (internal port), the performance for EF class traffic on the WAN link goes down to only 4 mbps regardless if is it 8xT1/E1 or a DS3 connections. Please help!
